Abstract:Human immunodeficiency virus type 1 (HIV-1) displays both interstrain and intrastrain genetic variability. Virus populations with extensive microheterogeneity have been defined as swarms or quasispecies. Many of the genomes within HIV-1 swarms appear to be defective in one or more genes required for viral replication. It is unclear to what extent defective viruses play a role in the process of HIV-1 infection or in the pathogenesis of AIDS. We have isolated two biologically active HIV-1 clones: LW 12.3, which …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
